Everything You Need to Know about Annulments
When a marriage breaks down, most people assume divorce is the only option. However, in certain circumstances, you may be able to get an annulment instead. If you're wondering whether an annulment might be right for your situation, this guide will help you understand everything you need to know.
What is an Annulment?
An annulment is a legal procedure that declares a marriage null and void, as if it never legally existed in the first place. Unlike a divorce, which ends a valid marriage, an annulment essentially erases the marriage from a legal standpoint. When an annulment is granted, the law treats the marriage as though it never happened.
This is an important distinction because it can have significant implications for:
Your legal status
Financial arrangements
Religious considerations
Future marriage prospects
Inheritance and wills
Many people seek an annulment for religious reasons, as some faiths don't recognise divorce but may accept an annulment. However, you don't need to have religious grounds to apply, the reasons for seeking an annulment are based purely on specific legal criteria.
What Is the Difference Between an Annulment and a Divorce?
While both end a marriage, they work in fundamentally different ways:
Key Differences:
Timing
Annulment: Can be applied for at any time after marriage, even within the first year
Divorce: Cannot be applied for until you've been married for at least one year
Legal Effect
Annulment: Declares the marriage was never legally valid or was defective from the start
Divorce: Ends a valid marriage that has irretrievably broken down
Grounds Required
Annulment: Must prove the marriage is either void (never legal) or voidable (defective)
Divorce: Simply requires a statement that the marriage has irretrievably broken down
Religious Recognition
Annulment: Often more acceptable to certain religious communities
Divorce: May not be recognised by some religious institutions
Impact on Wills
Void annulment: Does not revoke previous wills
Voidable annulment: Revokes wills like a valid marriage
Divorce: Revokes gifts to a former spouse
Choosing the wrong route can cause delay or prevent the outcome you’re seeking, so early advice is important.
What Is the Criteria for an Annulment?
To obtain an annulment in the UK, you must prove specific grounds that render the marriage either void or voidable. These grounds are set out in law and are quite strict, you can't simply choose to have your marriage annulled because you've changed your mind.
Void Marriages
A void marriage is one that was never legally valid from the start. For an annulment based on a void marriage, the marriage must fall into one of these categories:
1. You Were Too Closely Related
The couple were within the 'prohibited degrees of relationship'. This means you cannot marry:
Parents, grandparents, or children
Brothers or sisters (including half-siblings)
Aunts, uncles, nieces, or nephews
2. Either Party Was Underage
If the marriage took place on or after 27 February 2023, both parties must have been at least 18 years old
Before that date, those aged 16-17 could marry with parental consent
Any marriage where either party was under the legal age is automatically void
3. Required Formalities Were Not Followed
The marriage ceremony must comply with the Marriage Act 1949, including:
Proper licensing of the venue
Authorisation of the person conducting the ceremony
Correct procedures for banns, notices, or certificates
Marriage taking place in an approved location
4. One Party Was Already Married
If either person was already lawfully married or in a civil partnership at the time of the ceremony, the second marriage is automatically void. This is known as bigamy, and it applies even if the parties didn't know about the existing marriage.
5. Polygamous Marriage Issues
If a polygamous marriage was conducted outside the UK but either party was domiciled in England and Wales at the time, it will be considered void here.
Voidable Marriages
A voidable marriage is one that was initially valid but can be annulled due to certain defects. For an annulment for a voidable marriage, one of the following must apply:
1. Non-Consummation of the Marriage
The marriage hasn't been consummated (you haven't had sexual intercourse since the wedding) due to either:
Incapacity: One party is physically unable to consummate the marriage
Wilful refusal: One party refuses to consummate the marriage
Important note: This ground doesn't apply to same-sex marriages or civil partnerships.
2. Lack of Valid Consent
Either party didn't properly consent to the marriage because of:
Duress: You were forced into the marriage against your will
Mistake: There was a fundamental mistake about the nature of the ceremony or the identity of the other person
Mental incapacity: Either party lacked the mental capacity to understand they were getting married
Intoxication: One party was too drunk or under the influence of drugs to consent
3. Mental Disorder
Either party was suffering from a mental disorder (within the meaning of the Mental Health Act 1983) at the time of marriage that made them unfit to marry.
4. Venereal Disease
The respondent had a venereal disease in a communicable form at the time of marriage, and you didn't know about it.
5. Pregnancy by Another Person
The respondent was pregnant with another person's child at the time of marriage, and you didn't know about it.
6. Gender Recognition Issues
An interim gender recognition certificate has been issued to either party after the marriage
Or the respondent had an acquired gender under the Gender Recognition Act 2004 at the time of marriage, and you didn't know
When Can You Apply for an Annulment?
Timing depends on the type of marriage.
Void marriages
There is no time limit. Applications can be made at any point, although long delays may need explaining.
Voidable marriages
Strict time limits usually apply:
Three-year limit for cases involving lack of consent, mental disorder, venereal disease, pregnancy by another person, or acquired gender
Exception: The court may allow late applications where mental disorder is involved and it would be fair to proceed
Six-month limit if based on an interim gender recognition certificate
No time limit for non-consummation
How to Apply for an Annulment
Applying for an annulment is similar to divorce, but with additional legal steps and evidence requirements:
Complete and file Form D8N (currently paper-based only), setting out the legal grounds for annulment.
Provide a statement of case explaining why the marriage is void or voidable.
Submit supporting evidence where required (for example, medical evidence or witness evidence).
Court review and service – the court will check the application and arrange for papers to be served on your spouse.
Your spouse responds within the required timeframe, either agreeing to the annulment or disputing it.
Court consideration – if the annulment is contested, the court may request further evidence and list a hearing.
Conditional order – if the court is satisfied, it will make a conditional order of nullity.
Final order (decree of nullity) – at least six weeks later, you can apply for the final order, which legally confirms the annulment.
How Long Does the Annulment Process Take?
Most annulments take around 6–8 months, but longer if contested.
Typical timeline:
Application submitted
Spouse responds
Conditional order granted
Six-week waiting period
Final order issued
Disputed or complex cases can take 12 months or more.
What Happens If an Annulment Is Denied?
If the court refuses your application, you still have options.
Why an application may be refused
The legal criteria aren’t met
Time limits were missed
Evidence is insufficient
The court considers divorce more appropriate
Your options after an annulment refusal
Appeal, where there may be a legal error
Apply for divorce, if eligible
Seek a judicial separation, if divorce isn’t available
Submit further evidence, if permitted
Early legal advice can help you decide the best next step.

FAQs
Is an annulment quicker than a divorce?
Not always. Although you can apply for an annulment at any point after the marriage (including within the first year), the process itself is not usually faster. Most annulments take around six to eight months, and some can take longer if the case is complex or contested.
Does an annulment mean the marriage never happened?
Legally, an annulment treats the marriage as if it never existed. However, this does not remove the practical consequences. Financial matters still need to be resolved, and if there are children, all parental responsibilities continue as normal.
Can I get an annulment because I regret the marriage?
No. Regret or a change of heart is not enough. Annulments are only granted where specific legal grounds apply. Any “mistake” must be fundamental, such as not understanding you were entering into a marriage or being mistaken about the identity of the person you married.
Is an annulment easier to get than a divorce?
In many cases, no. Annulments often involve a higher legal threshold because you must prove one of the strict statutory grounds. Divorce, by contrast, only requires a statement that the marriage has irretrievably broken down.
Will I still need to deal with finances if my marriage is annulled?
Yes. Even though the marriage is treated as void or voidable, the court can still make financial orders where appropriate, including decisions about property, savings, and ongoing support.
